WARREN TV. DUTGHER, OF MILFORD, MASSACHUSETTS.

ROLLER-TEMPLE FOR LOOMS.

Specification of Letters Patent No. 17,559, dated June 16, 1857.

To all whom it may concern.'

Be it known that I, WARREN W. DUTCHER, of Milford, in the county of`Worcester and State of Massachusetts, have invented an Improvement inthe Roller-Temple Cases for Looms; and I do hereby declare that the sameis fully described and represented in the following specification andthe accompanying drawings, of which- Figure l exhibits a side elevationof a temple containing my invention; Fig. 2, a transverse and verticalsection of it, such being taken through and in line with the axis of itstoothed roller; Fig. 3, a transverse section of the roller case showingthe recess or space therein to be hereinafter described, the roller notbeing shown in this figure.

In these drawings A, exhibits the toothed roller of the temple, while B,represents the case within which the said roller is situated, and fromwhich projects the bearing or shaft, C, on which the roller is supportedand revolves while in operation, such shaft being extended from the endpart or head a, of the case as shown in the drawings. This case isconstructed with a circular or cylindrical recess b, formed or sunkwithin the end part a, and of a diameter just suiicient to receive theinner end of the roller and to admit said roller, C, to freely revolveon its shaft. The depth of this recess may be about one tenth of aninch. As it extends entirely around the roller, it serves, during theprocess of weaving, as a guard to prevent the loose warp or fillingthreads from getting and gathering between the head or end of the rollerand the part, a, of the case against which such end revolves. In thecommon roller temple as ordinarily constructed, without any such recessor guard, the loose warp or filling threads by getting between theroller and head of its case frequently arrest the motionv of the rollerand thereby cause the cloth to become torn or injured by the points ofthe roller while the cloth is being drawn forward. Besides this, when aroller becomes so clogged much time and labor are required to beexpended in order to remove the obstruction. With my improved case theabove mentioned difliculty is not likely to ensue, practice havingdemonstrated the invention to be one of great practical value in the artof weaving, to which it appertains.

That I claim and desire to secure by Letters Patent, is

The abovedescribed improved roller temple case made with a cylindricalrecess for the reception and protection of one head or end of thetoothed roller in manner as specified.

In testimony whereof, I have hereunto set my signature.
